Dear experts,

We have our application running on 7 Web Sphere application servers running clustering environments. How we need to count number of active sessions at any given point in time?

Thanks,
SR

This can be achieved by SMS (Session Mgmt Server), which comes bundled with TAM for eBusiness. But simple one way to achieve this is:

1. Implement a HTTP Session Listener class, which will get called whenever a new session is created or destroyed.

2. Create a table in the database, which will store the session count.

3. Increment counter every time a new session is created and decrement every time a session is destroyed.

 
It is sorta covered in the JavaRanch Style Guide.
